Creating a methodology so city-level sanitation investment decisions can be supported by a better understanding of pathogen flows

This Policy Brief summarises an initial research study which developed a conceptual model of faecal pathogen pathways in urban environments.

The proposed model uses a “source-pathway-receptor” approach: it considers release of pathogens into the environment, transport in the environment, and eventual human exposure.

The model can potentially provide a framework for comparing the relative impacts of different sanitation options on health; the next step should be to test the approach in a real city.

This research was led by the University of Technology Sydney (UTS).
